Introduction to OLEDs

OLED (Organic Light Emitting Diodes) is a new display technology. OLEDs are made from organic materials that emit light when electricity is applied. OLEDs are used to create thin, efficient and beautiful displays. 


OLEDs can be used to create televisions. Like LCD, they can be used to make High-Def TVs (HDTVs). Currently only Samsung has discussed HDTV OLEDs. Samsung's roadmap spells such televisions by 2010.

Samsung 40 HD-AMOLED TV Prototype

In fact Samsung has already shown an HDTV OLED - a 40" prototype, back in October 2008. The resolution is 1,920 by 1,080, and the contrast rate is 1,000,000:1.

There are also rumors that Panasonic is working toegether with Toshiba on OLED TVs. These will be HDTVs, and will be available in 2 years.

OLED HD microdisplays

HD is not just for TVs. eMagin, already shipping OLED microdisplays for many years, are working on higher-than-HD resolution microDisplays. These little displays make their ways into military equipment, but also might be available for VR goggles in the future.

OLED TVs today

Today only Sony is selling an OLED TV, the 11" XEL-1. This is actually more of a prototype or demonstration set - it costs 2,500$, and they only make around a thousand a month.
